Multicasting slowed up significantly
Before half term we had no problems ghosting a single machine using multicast (it stops us having to remember to change the settings depending on how many macines we are ghosting).
After half term, the speed has significantly slowed, we could ghost a machine in around 20-25 minutes and now anything less than 2hrs is an achievment!
Nothing has changed on the switch side of things, the server had windows updates and dell hardware updates. I've since rolled back to the previous versions of NIC driver and firmware on the server in case that was the cause.
Other things I've tried, plugging the ghost server directly into our Core switch (as apposed to the server switch) becuase we have ip multicast-routing and ip pim-dense on our Core (it's a HP 5406zl), updated the server bios, tried placing the machine on different vlans, we've tried ghosting a machine on a different part of the network and all of these produce the same results - slow speed.
On Unicast we have no problem.
The server and client and I am trying to ghost are on different vlans but everything is setup as it was before half term when we had no issues.
Anybody have any ideas?
